Impact factor (IF) is a concept dating back over half a century, created to evaluate the impact of a journal within a particular scientific field. In spite of limitations, IF remains a widely used metric for journals to establish the average number of citations for articles published in a journal. The Irish Journal of Psychological Medicine (IJPM) recently received an IF of 5.1, the first IF for the journal. We believe that this is a reflection of the hard work and dedication of our authors, reviewers, publishers and editorial board. The IJPM is the official research journal of the College of Psychiatrists of Ireland, and while psychiatry is the primary discipline of the journal, the current multidisciplinary approach will continue into the future. The journal has a strong Irish and international readership; while the journal will continue to publish research with an Irish focus, the editorial team are aware of the importance of ongoing global contributions to ensure the journal maintains high-quality publications of an international standard. This is an exciting time to be involved in mental health research, and the journal will continue to publish cutting edge themes with the goal of improving mental healthcare in Ireland and beyond.
